I suspect the locked thread you listed was locked mostly due to preludes post and a complaint regarding it. I will find out for sure though. I probably wouldn't have locked it personally, but there may be circumstances I am unaware of.
There are 6 deleted threads on the front page of = 10, and 4 more on the second page. 8 of those threads belong to this banned user:
https://everquest.allakhazam.com/poster.html?user=1757171 who was a sockpuppet for This banned user:
https://everquest.allakhazam.com/poster.html?user=1587072 Who was banned for "Racist, and really disturbing pro rape posts." according to the notes field. I banned the origional account myself. As the last topic the sockpuppet account posted was "whats a negro lot?" I am quite certain that is not a poster we need active in FFXI main.
Banning an account immidiatly deletes all posts associated with that account, including new topics. There were also several gilseller threads deleted in there.
Regarding the post you linked ThePsychoticOne, the thread itself was one of the posts made by the banned user listed above. The post inside that by noodles that was deleted was deleted because it was somewhat less than welcoming to new posters. At the time it was posted noodles could not have known that it was a sockpuppet about to be banned, and had it been an actual new poster, comments like that can tend to make them uncomfortable and stop posting. I concur with the deletion of that post. The bottom line is the FFXI forum, like most of the forums around here is losing mainstay members faster than they can be replaced. We are very comitted to bringing in new people to maintain the forum at a level where it can sustain its own rythem of posts and replies and not slowly dwindle away.
In this case, since it was a sockpuppet, it didn't matter in the end.
